Understanding the PHP Function ftp_exec()

We are here to help you understand the PHP function ftp_exec() and its usage in your projects.

What is ftp_exec()?

The ftp_exec() function is a built-in PHP function that allows you to execute a command on a remote FTP server. The function takes two parameters:

1. ftp_stream: The connection identifier returned by the ftp_connect() function.
2. command: The command you want to execute on the FTP server.

The function returns a boolean value. If the function is successful in executing the command, it returns true. Otherwise, it returns false.

Syntax of ftp_exec()

The syntax of the ftp_exec() function is as follows:

bool ftp_exec ( resource $ftp_stream , string $command )

The ftp_exec() function takes two parameters: ftp_stream and command. The ftp_stream parameter is the connection identifier returned by the ftp_connect() function. The command parameter is the command you want to execute on the FTP server.

Usage of ftp_exec()

To use the ftp_exec() function, you need to establish a connection to the FTP server using the ftp_connect() function. Here's an example:

<?php

// Set up an FTP connection
$conn = ftp_connect('ftp.example.com');

// Login with your FTP credentials
ftp_login($conn, 'username', 'password');

// Execute a command
ftp_exec($conn, 'ls -al');

// Close the connection
ftp_close($conn);

In this example, we establish a connection to the FTP server using the ftp_connect() function. Then we log in using our FTP credentials using the ftp_login() function. Finally, we execute a command using the ftp_exec() function and close the connection using the ftp_close() function.

Error handling in ftp_exec()

It's important to handle errors properly when using the ftp_exec() function. If the function returns false, it means that the command couldn't be executed for some reason. Here's an example of how to handle errors:

<?php

if (ftp_exec($conn, 'ls -al') === false) {
    echo "Failed to execute the command.\n";
} else {
    echo "Command executed successfully.\n";
}

In this example, we check the return value of the ftp_exec() function. If it's false, we display an error message; otherwise, we display a success message.
